# [gamja]

A simple IRC web client.

## Usage

Requires an IRC WebSocket server.

First install dependencies:

    npm install --production

### [soju]

Add a WebSocket listener to soju, e.g. `listen wss://127.0.0.1:8080`.

Configure your reverse proxy to serve gamja files and proxy `/socket` to soju.

### [webircgateway]

Setup webircgateway to serve gamja files:

```ini
[fileserving]
enabled = true
webroot = /path/to/gamja
```

Then connect to webircgateway and append `?server=/webirc/websocket/` to the
URL.

### nginx

If you use nginx as a reverse HTTP proxy, make sure to bump the default read
timeout to a value higher than the IRC server PING interval. Example:

```
location /socket {
	proxy_pass http://127.0.0.1:8080;
	proxy_read_timeout 600s;
	proxy_http_version 1.1;
	proxy_set_header Upgrade $http_upgrade;
	proxy_set_header Connection "Upgrade";
	proxy_set_header X-Forwarded-For $remote_addr;
	proxy_set_header X-Forwarded-Proto $scheme;
}
```

If you are unable to configure the proxy timeout accordingly, you can set the
`server.ping` option in `config.json` to an interval, in seconds, between which
gamja will send opportunistic pings.

### Development server

Start your IRC WebSocket server, e.g. on port 8080. Then run:

    npm install
    npm start

This will start a development HTTP server for gamja. Connect to it and append
`?server=ws://localhost:8080` to the URL.

## Query parameters

gamja settings can be overridden using URL query parameters:

- `server`: path or URL to the WebSocket server
- `nick`: nickname
- `channels`: comma-separated list of channels to join (`#` needs to be escaped)

Alternatively, the channels can be set with the URL fragment (ie, by just
appending the channel name to the gamja URL).

## Configuration file

gamja default settings can be set using a `config.json` file at the root:

```js
{
	// IRC server settings.
	"server": {
		// WebSocket URL or path to connect to (string).
		"url": "wss://irc.example.org",
		// Channel(s) to auto-join (string or array of strings).
		"autojoin": "#gamja",
		// Controls how the password UI is presented to the user. Set to
		// "mandatory" to require a password, "optional" to accept one but not
		// require it, and "disabled" to never ask for a password. Defaults to
		// "optional".
		"auth": "optional",
		// Don't display the login UI, immediately connect to the server
		// (boolean).
		"autoconnect": true,
		// Interval in seconds to send PING commands (number). Set to 0 to
		// disable. Enabling PINGs can have an impact on client power usage and
		// should only be enabled if necessary.
		"ping": 60
	}
}
```
